基于风电机组可靠性的风电场平准化成本模型研究

考虑综合风电场总体运行成本、风电机组可靠性及风电场发电量等多个维度,从风电场全生命周期视角出发,建立基于风电机组可靠性的风电场平准化成本模型,并通过算例分析得出,提升风电机组可靠性可降低风电机组的故障维护成本,提高风电场运行小时数,进而降低风电场平准化成本。在此基础上测算当前阶段风电实现平价上网需达到的利用小时数,最后给出促进风电发展的合理化建议。

RESEARCH ON LEVELIZED COST MODEL OF WIND FARMS BASED ON WIND TURBINE RELIABILITY

As the reform of the electricity market continues to deepen, the wind power industry faces the dual pressures of “subsidy decline” and “reducing wind power cost”. The key to realizing wind on-grid price equal to the benchmark price of thermal power is to reduce the cost of wind power and improve its competitiveness in the power market. This paper comprehensively considers the overall operating cost of wind farms, the reliability of wind turbines, and the power generation of wind farms, establishes a Levelized Cost of Energy model for wind farms based on wind turbine reliability from the perspective of the full life cycle of wind farms. With the help of a quantitative analysis example, it is concluded that improving the reliability of the wind turbine reliability can reduce the fault maintenance cost and increase the operating hours of the wind farm, which achieve the goal of reducing the cost of Levelized Cost of wind power. On this basis, the wind power utilization hours meeting to on-grid price equal to the benchmark price of thermal power is estimated. Furthermore, the paper gives suggestions for promoting wind power development.
